Waisda? is an online video annotation game-with-purpose launched in May 2009. Users are invited to tag what they see and hear and receive points for a tag if it matches a tag that their opponent has entered. Waisda? uses the principle of crowdsourcing in order to collect user tags regarding video material from the The Netherlands Institute for Sound and Vision (Nederlands Instituut voor Beeld en Geluid). These tags are used to describe videos according to their content and furthermore increase the findability of content. The scope of the thesis is to conduct research for finding ways of improving the game experience of Waisda? and finding ways to reduce tag ambiguity during and after game. Specifically, the aim of the thesis is to propose new mini games, play modes and an achievement system that can be integrated to Waisda?, which will in turn enhance the gameplay and replayability of the game as well as the motivation of players to keep playing. Furthermore, focus will be given in methods for reducing tag ambiguity during/after the game. This involves the process of identifying and suggesting an efficient structure for tags in order to reduce cases of acronyms, multiple words, synonyms or plural vs singular tags.
